Legacy Prison Cases: Internment, Blanket Protest & CR Gas
At Ó Muirigh Solicitors, we represent former prisoners and their families in historical cases arising from detention, mistreatment, and the use of force in prisons during the conflict in the north of Ireland. This includes cases related to Internment without trial (1971-1978), the Blanket and No-Wash Protests (1976-1981), and the use of CR gas in Long Kesh in 1974.
Our legal team is at the forefront of efforts to secure justice, recognition, and redress for those who were subjected to unlawful detention, degrading treatment, and the denial of basic rights while imprisoned. We have acted in a number of landmark legal cases and public inquiries which continue to shape the legal and historical understanding of this deeply significant era.

- CR Gas Use in Long Kesh (1974)
